Postulate for airtightness limits in large buildings

Submitted by on Tue, 11/05/2013 - 18:32

DIN 4108-7 requires a limit of q50 ≤ 3.0 m³/m²h for the air permeability of large buildings. Even stricter limits with respect to q50 can be found at DGNB [German Sustainable Building Council] and in the Swiss MINERGIE Standard.
It is the objective of this presentation to develop awareness of this topic in the audience and to give recommendations as to which limits can be applied to new building projects.
